Bar Charts: pond life

Further Challenges

• Can you estimate how many individual eggs their are in the frogspawn pictured below?

• Rebecca, Stephanie and Polly found some frogspawn that contained 318 individual eggs. They wanted to to divide the frog spawn equally between themselves. (They each had a pond in their back garden and were keen to attract wildlife into it.) Is this possible?
• Have a go at the fabulous Lily Pond investigation on the NRICH website, which encourages you to work systematically.’
